Karhu is a Finnish brand with a compact size range: nine unisex sizes from EU 37 to 47. Short, but not without its quirks: eight of those nine sizes correspond to a different EU size than a standard conversion would suggest.
Small but different
At Karhu, US 9 is EU 42, while the standard chart uses 42.5. That pattern of being half a size smaller continues through almost the entire range.
UK sizes are less problematic: there are only two discrepancies across nine rows. If you know your UK size, you’ll get closer to the correct fit than by relying on your EU size.
One range for everyone
Karhu doesn’t publish separate men’s and women’s size ranges, but uses a single unisex scale. That makes ordering simpler, since the same US size always means the same thing here.
The range is limited, though: the brand publishes no sizes below EU 37 or above 47.
Fit
With Karhu, the sizing advice depends on when the sneaker was released — an unusual but important detail.
Current releases fit true to size. For colorways released before 2025, however, Karhu itself recommends going up a full size. Since older colorways are still widely available from comparison sites and outlets, this is more than a theoretical concern: be sure to check which release year you’re looking at.

Still not sure?
Measure your foot from heel to longest toe and compare that length with the cm column. Do it while standing, at the end of the day, and measure both feet. Your larger foot determines your size.
Once you know your size, you’re just two clicks away. Enter it in the filter and you’ll only see shops that have your size in stock, starting with the lowest price. No more keeping multiple tabs open to compare prices, and no guessing at checkout.
Frequently asked questions about Karhu sizing
Does Karhu run big or small?
Karhu assigns the same foot a lower EU size than the standard chart: US 9 is EU 42 instead of 42.5. Eight of the nine sizes differ in this way.
Does Karhu have separate men’s and women’s sizes?
No, Karhu publishes a single unisex range from EU 37 to 47. The same US size therefore always corresponds to the same EU size.
Is my UK size correct for Karhu?
For the most part, yes: there are two discrepancies across nine rows, compared with eight in the EU column. The UK column is the most reliable here.
